Just did an update check on my Surface Pro 2, and I noticed a System Hardware Update available to download (it wasn't large, around 200-400kb). I can't find any record of it online yet, but when looking at the update history, the update has a date of 10/24/2013. I was wondering if this was the firmware reversal? I haven't made any changes to my hardware, but it just as well may be something else. Any thoughts?
